Microphone too quiet

I have a Headset with a USB Transceiver, the earphones work perfectly well, only the microphone is far too quiet, even on 150% volume in pavucontrol I use pipewire as the audio system Any idea what the issue might be? here is the config: dotfiles/.config/nixos/configuration.nix at c644a6ba57b90d07798f1310a286d741e499a767 · Zemrod/dotfiles · GitHub
